A remote controller (10) according to an aspect of the present invention includes a speaker (11), an information receiver (18), a controller (19) and a display (13). The speaker (11) is configured to send an ultrasonic signal (Ω) that controls an operation of at least one in-vehicle device (51 to 54). The information receiver (18) is configured to detect information related to noise sound inside a vehicle (100). The controller (19) is configured to calculate a propagability index of the ultrasonic signal (Ω) from the information related to noise sound. The display (13) is configured to display the propagability index as communication quality level of the ultrasonic signal (Ω). The information receiver (18) is configured to measure degree of change in operating mode of the at least one in-vehicle device that changes the operating mode based on the ultrasonic signal (Ω). The controller (19) is configured to recalculate the propagability index based on the degree of change and update display of the communication quality level.
